WOOD-BUNDLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 294,125, dated February26, 1884. Application filed June 25, 1883 (Yo model.)

. of New York city, in the county and State of New York, have inventedcertain new and useful Improvements in \Vood Bundling Machines, of whichthe following is a specification.

My improved machine is on the general plan set forth in the patent to medated June 5, 1866, No. 55,282. The present invention lies inimprovements in the arrangement. Instead of overhanging the foot-leverwhich receives the pressure of the foot and transmits-through togglesthe powerful compressive strain to the bundle of wood which is about tobe tied, I

mount such lever centrally in the working parts. I mount the lever incylindrical bearings in a box, which box moves up and down in the slotin the fixed framing. The crossbar oryoke which engages with the strapand is depressed by the treadle-lever is arranged obliquely to thelever, and the strap and cradle are correspondingly oblique. Thisaffords greater facility for the putting in of the wood and taking outof the bundle, and does not interfere with the tying of the string. Italso allows the operator to see the work more easily than heretofore. Inthe most complete form of the invention, the strap which, beingdepressed by the treadle-lever, compresses the bundle of wood, isdouble, with sufficient space between for the string. a This compressesthe bundle on each side of the string, and makes, obviously, a moreperfect job than the former plan of compressing the bundle only on oneside, and effecting the tying where the bundle is flaring. In the formerconstruction the gage or adjustable back was mounted on the table,leaving a cavity between the cradle and itself, which was liable toreceive sticks of wood and delay the work. In my improved machine thegage is mounted on the cradle. In no stage of adjustment is there anycavity between the cradle and the gage. The strap is connected to thecross-head by pinching-screws, re-enforcing clamps being employed on theends of the straps below the cross-head, to aid in holding the strapvery strongly.

The accompanying drawings form a part of this specification, andrepresent whatI consider the best means of carrying out the invention.

through certain parts on theline y z in Fig. 1.

Similar letters of reference indicate like parts in all the figures.

A is a fixed frame, and A a casting, which Fig. 3 is a horizon I term acradle, which receives the wood.

This cradle is mounted obliquely upon the frame A, as clearly shown inFig. 2, and is of sufficient length to allow the gage B to be mountedthereon, being adjusted in the slot 2) and held by the binding-screw b.The lower portion of the gage B is rounded, to form the counterpart ofthe upper face of the cradle. The sides of the cradle are recessed toreceive a strap, 0, which is double at itsupper end, as indicated by cc". The lower ends of the strap are single, and are held bybindingscrews 0 in the ends of a skewed cross-head, G. (Shown in plan inFig. 4.) This mode of attachment allows the strap to be rapidly shiftedup and down to the considerable eX- tent required in changing suddenlyfrom large to small bundles and back again, but without the addition nowto be described it is liable to slip under the great strain imposed by astrong .operator with the great advantage due to the toggle action.

H are strong knobs or clamps fitted on the lower ends of the straps, andsecuredby binding-screws h. These serve to re-enforce the union of thestrap 0 with the cross-head O, and make it perfectly reliable. The leverD turns on the trunnions d, and is arranged to be strongly depressed bythe foot to throw the toggles E E nearly into line, and thus to effectthe required strong depression of the cross-head O, and of the connectedduplex strap C. It will be understood that the string (not represented)is introduced between the duplex parts of the strap 0 c c and allowed tosink into the proper recess in the cradle. The wood is placed in thecradle in proper quantity to nearly fill the space under the strap whilethe strap is in its highest position, the lever D being previouslyelevated and engaged on the fixed hook J. When a suficient quantity ofwood is in the cradle and the endsv of all the pieces are pressedagainst the gage B, the lever D is given a sufficient lateral movementto disengage it from the hook J, which falls somewhat by gravity. Then,the foot being applied, it is depressed to the floor, and the tying ofthe compressed bundle is effected. Next the lever D is released by thefoot, lifted by the hand, and engaged by the hook J. The bundle islifted out, a new string inserted, and the operation repeatedindefinitely. The slots a in the guides A are considerably wider thanthe trunnions (1.

Instead of allowing the trunnions to bear directly against the sides ofthe slot, they are inclosed in boxes G, which are received in the slotsand present wide bearings, so that they move smoothly up and downtherein.

These parts may be finished by machinery, if preferred; but myexperiments indicate that it will not be generally necessary.

I prefer that the links E E, which together constitute a double toggle,shall not come quite in line with each other before the treadlelever Dbears on the floor. The arrangement should be such that 011 removing thefoot from the lever D it will spring up by the reaction of the bundle ofwood acting through the toggle. A deXterous operator will stoop down andcatch it during its upward movement and continue it until it is engagedon the hook J.

The fact that the strap 0 is in two parts, with space between them forthe string to be applied and tied, is especially important on the veryshort lengths and large bundles which are now in demand. The gage beingproperly formed to match the cradle, and being mounted and adjustedthereon, allows its being much more firmly fastened than when it issecured on the table, as in the former plan.

I claim as my invention 1. In a wood-bundling machine, the cradle A,cross-head C, and one or more straps, 0'0", arranged askew relatively tothe shaft d, and

lever D, in combination therewith, and with the toggle-links E E, asherein set forth.

2. In a wood-bundler, the cradle A, having the slot 1), in combinationwith the fasteningbolt 1), and with a gage, B, having its lower outlinecurved to match the cradle and allow it to be adjusted forward andbackward there on, as herein specified.

3. The strap 0, single at each end and double at and near the .middle,bent as shown, and combined with the cross-head or yoke C, and suitablemechanism for operating it up and down, and with the cradle A and gageB, as herein specified.

4. In a wood-bundler operating with the aid of a strap, 0, andtreadlelever D, the cross-head C, and adjusting means 0, in com binationtherewith, and with the re-enforcing clamps H and their adjusting means71, as herein specified.

In testimony whereof I have hereunto set my hand, at New York city, NewYork, this 20th day of June, 1888, in the presence of two subscribingwitnesses.
